P-S model is designed to have a massive-use solution, based on a concept of strength and time durability. This machine is suitable for manual or automatic operations thanks to the additional accessories that can be installed. The structure is correctly stiffened in order to accept also heavy parts (heavy duty design). The internal walls of the chamber are lined with rubber sheets (thickness 3 mm) in order to prevent the machine wear and reduce the noise level. The machine is designed to works with corundum, glass beads, ceramic beads, plastic granulates, nut shells. The lighting is placed on the roof of the cabin (far to the operator window not to disturb the operator visibility), protected with safety glass. The operator station is equipped with two glasses (one externally fixed on the welding construction thanks a rubber sealing and one internally on a structure easy to replace).
